Resumo: The use and management of the soils have caused physical-water changes of them. The evaluation of these modifications is necessary for the dimensioning of the physical quality of the soils, in order to characterize and understand the dynamics of the changes in the environment. In this sense, this study has the goal of characterize and evaluate the influence of different systems of use and management of the soil. The study was conducted at the São João site, located in the city of Salto de Pirapora, SP, Brazil, where the mechanical resistance to penetration, hydraulic conductivity and soil infiltration were evaluated over a year in three management systems: (1) Agroforestry System (SAF); (2) lytic planting (LIC) and (3) area in transition for banana plantation (PAS). In each treatment, the soil cover was also measured using a 0.24m² quadrant, as well as undisturbed soil samples in the 0-10 cm layers to determine their density and humidity. Rainfall data were recorded monthly to correlate with the physical-water attributes of each treatment. The systems with the highest and most frequent management (SAF and PAS) presented better results in relation to soil quality than the system with lower management (LIC), except for the parameters humidity and soil cover where the LIC presented better conditions. The physical characteristics of SAF and PAS were similar to each other and different from the LIC area. The physical characteristics of SAF and PAS were similar to each other and different from the LIC area. Thus, it can be concluded that DS, K, VI, RMSP in SAF and PAS soils showed a better quality in relation to LIC.
